TRUSTLESS, DECENTRALISED DISTRIBUTED LEDGER
A blockchain is a distributed ledger which does not depend on a centralised authority to store, secure and share data. Instead, the data is encrypted and stored in a network made up of nodes. As you do not need to share your personal identifiers or your private health information with a centralized authority, the network is referred to as trustless. A decentralised network also has the advantage of being less vulnerable to hacking or outages since it does not depend on a single centralised server.
SELF-SOVEREIGNTY OF PRIVATE HEALTH INFORMATION
Everyone on the network has ownership and self-sovereignty of their own private health information (PHI). Each individual holds their private keys which gives them access to their PHI stored on the blockchain. There are no personal identifiers stored on the blockchain, instead the data is assigned to the public key of the individual. This creates a network where everyone can feel safe and confident to share data relating to their health.
SHARING OF DATA IN A PEER-TO-PEER MANNER
The sharing of anyone’s data is performed in a consented and entirely peer-to-peer manner. No centralized party is involved in the transaction of sharing PHI between individuals. The sharing of data does can be with anyone we choose to share that data with and we have full control to revoke that access when we choose to do so.
AUTHORSHIP TRANSPARENT AND TIMESTAMPED EVENTS
The data stored on the blockchain is trustworthy as there is an open authorship of which healthcare provider wrote the on-chain data. Namely, every healthcare provider takes accountability and responsibility of ensuring the data is accurate and correct. Each entry onto the blockchain is timestamped meaning the exact date and time when the data was recorded is stored with every transaction. Once data is written to the blockchain it remains there immutably. The data cannot be altered once it has been written. Any corrections or updates are stored as new transactions resulting in a data trail that is auditable and traceable.
What is a Covid Passport?
An important future step towards reopening our borders, allowing safe travel and ensuring safe access to public areas is to develop a trusted network where people can share their covid-19 related data. The development of a digital “passport” using a permissioned blockchain technology to decentralize storage and allow peer-to-peer sharing of data we believe is the best solution.
The Health Passport is a research project led by the principle investigator Dr Marten E. Brelen at The Chinese University of Hong Kong. The project is research grant funded from the covid-19 one-off Project Impact Enhancement Fund (PIEF). Beta testing of the health passport is currently ongoing at the vaccination centre at CUHK Medical Centre.
What data can I store on the Passport?
The following data can be stored on the blockchain and shared with other individuals by the beta version of COVID-19 passport:
COVID-19 test results
Antibody/immunity tests result
Body temperature checks
